US President Donald Trump is giving serious thought to restarting the war with Iran due to the regime's approach to negotiations, according to aides close to him who spoke with CNN on Monday.

The network highlighted that the most recent Iranian proposal - labeled 'unacceptable' by Trump - combined with the ongoing blockade of the Strait of Hormuz and splits within Iran's leadership, are major reasons compelling the president toward renewed conflict.

Speaking to reporters Sunday, Trump described the ceasefire as hanging by a thread following the new proposal. He asserted that he possesses a strategy and insisted Iran must never acquire nuclear weapons.

Officials noted stark differences in timelines between Washington and Tehran, with the Iranian regime convinced it can better endure economic sanctions than further combat.

Following Sunday night's US security cabinet session, insiders indicated slim odds of imminent strikes, suggesting any shift would likely follow Trump's upcoming trip to China.

Hawks versus doves in the security cabinet

CNN's coverage revealed a classic hawk-dove split during the cabinet discussions, with Trump's advisors divided into two distinct camps.

Hawks seek to lean on Pakistani intermediaries to ensure Iran grasps the gravity of US warnings, viewing a return to hostilities as a viable option.

Over recent weeks, these officials have questioned whether Pakistan is relaying Trump's frustration with the talks as forcefully as his public remarks.

Conversely, other aides urge the president to allow diplomatic efforts room to succeed and refrain from strikes amid active discussions.
